Question

Diketahui rumus fungsi f(x) = 4x + 5 dan g(x) = 3-5x . nilai f(3)-g(2)= ...
a. 10 c. 17
b. -7 d. 24

Answer 1

F(3) = 4*3 + 5 = 12 + 5 = 17
g(2) = 3 - 5*2 = 3 - 10 = -7
f(3) - g(2) = 17 - (-7) = 17 + 7 = 24

Answer 2

F(x)=4x + 5
g(x)=3-5x

f(3)=4(3)+5=12+5=17
g(2)=3-5(2)=3-10=-7

f(3)-g(2)=17-(-7)=17+7=24
